The
cap of the mushroom is wide; oval at first, becoming convex, typically with a central bump; sticky; brilliant red or orange, fading to yellow on the margin; typically without warts or patches; the margin lined for about 40–50% of the cap's radius. The red pigment fades from margin toward the center with age. The
gills are moderately crowded to crowded, orange-yellow to yellow-orange to yellow. They are free from the stem or slightly attached to it; yellow to orange-yellow; crowded; not bruising. The short gills are subtruncate to truncate. The
stipe measures , is yellow and decorated with orange fibrils and patches that are the remnants of a felted extension of the limbus internus of the otherwise white volva. The
spores measure (7.0-) 7.8–9.8 (-12.1) × (5.2-) 5.8–7.5 (-8.7)
μm and are broadly ellipsoid to ellipsoid (rarely subglobose or elongate) and inamyloid.
Clamps are common at bases of
basidia. The flesh looks whitish to pale yellow and does not stain on exposure.
